This industry funded and written study reports on 53 patients with severe Covid-19 that got expanded use remdesivir in the USA, Europe and Japan.
Short answer… they got it and they got better.
Of course, we have no idea if remdesivir did anything. This was not a trial. There was no control group, no randomization, no blinding, nothing, zip, nada.
But fear not. Gilead Sciences, the manufacturer of remdesivir, is currently conducting a large phase 3 randomized clinical trial. They plan to enroll 6000 patients at 179 sites and have it finished by a “holy shit fast” May 2020!
Fortunately, most of their recruiting sites are based in the USA where there is plenty of patients to study. (Thanks Donald). Studies out of China have now been suspended or terminated due to low patient numbers.
A search of www.clinicaltrails.gov indicates the primary outcome of the phase 3 trial is an odds ratio of improvement on a 7-point ordinal scale. This type of analysis has incredible statistical efficiency. Along with 6000 patients, this study will have the power to demonstrate miniscule differences in patient outcomes.
Do you know what else Gilead Sciences developed?
Tamiflu.
Gilead licensed the drug to Roche in 1996 on return for royalties. Despite hardly any evidence of efficacy, it was a blockbuster that saw the world stockpile billions worth during H1N1.
Now if there was just some other global scare that might sell remdesivir? Hmmmm….
Ok, I am being paranoid. But I do think we need to be careful when this study is soon published and not let emotions & politics trump science. (Pun intended.)
Nevertheless, I genuinely hope this drug works. We have antivirals that have cured hepatitis C. We’ve put the brakes on HIV. In theory, remdesivir looks quite promising. It is an RNA polymerase inhibitor specifically designed to treat coronaviruses. Perhaps there is some hope.
So, watch this space.
But be skeptical.

Dr Brian Doyle is an emergency physician originally from the United States but now very much calls Tasmania his home. Unfortunately, it will now be a bit more difficult to deport him from the country as he passed his Australian citizenship test a few years ago. (He was able to answer that Phar Lap won the Melbourne rather than the Davis Cup). His main interests are mostly the clinical aspects of emergency medicine but also in education, ultrasound and critical appraisal of the literature. He spends much of his time annoying people to help out with conferences. |
